问题
I am having an issue with a task I'm supposed to do, I'm supposed to send MMS using our own interface on android 2.1 so as you can guess calling the default Activity is out of the question. So my question, is there a way to programatically send MMS using the android SDK without calling their intent, I tried importing the MMS app in eclipse but most of the classes are com.google.android which means they are not open sourced, so I have no idea how to get them if possible, or, how to mimic them. I was even thinking of using reflection to load them from Dalvik, but I think that this is a final effort and may not bring results.
any ideas?
btw, I found
How to send image via MMS in Android?
Sending MMS into different Android devices
but they do not work.. (with out the proprietary classes)
回答1:
Although this question was left unanswered for a while, I kinda found a way back then, just forgot to post. however I got the original MMS app and crippled the binary classes and added corresponding requirements to finish since most of them were private to the build system. The ONLY way do make an mms sender in android (that I know of) is to build the app with the source tree. In that manner you will have access to the restricted MMS functions and it is generally very easy since there is a MMSManager in the source it's self, although this is not public in the sdk. I know my answer is a bit vague, but for those of you going down this path.. prepare for some bumps on the road.. :)

Like SmsManager there is something like MmsManager api which is not being exposed by android framework.
So to send MMS first you have to acquire MMS netwotk and then make http calls.
/**
* Synchronously acquire MMS network connectivity
*
* @throws MmsNetworkException If failed permanently or timed out
*/
void acquireNetwork() throws MmsNetworkException {
Log.i(MmsService.TAG, "Acquire MMS network");
synchronized (this) {
try {
mUseCount++;
mWaitCount++;
if (mWaitCount == 1) {
// Register the receiver for the first waiting request
registerConnectivityChangeReceiverLocked();
}
long waitMs = sNetworkAcquireTimeoutMs;
final long beginMs = SystemClock.elapsedRealtime();
do {
if (!isMobileDataEnabled()) {
// Fast fail if mobile data is not enabled
throw new MmsNetworkException("Mobile data is disabled");
}
// Always try to extend and check the MMS network connectivity
// before we start waiting to make sure we don't miss the change
// of MMS connectivity. As one example, some devices fail to send
// connectivity change intent. So this would make sure we catch
// the state change.
if (extendMmsConnectivityLocked()) {
// Connected
return;
}
try {
wait(Math.min(waitMs, NETWORK_ACQUIRE_WAIT_INTERVAL_MS));
} catch (final InterruptedException e) {
Log.w(MmsService.TAG, "Unexpected exception", e);
}
// Calculate the remaining time to wait
waitMs = sNetworkAcquireTimeoutMs - (SystemClock.elapsedRealtime() - beginMs);
} while (waitMs > 0);
// Last check
if (extendMmsConnectivityLocked()) {
return;
} else {
// Reaching here means timed out.
throw new MmsNetworkException("Acquiring MMS network timed out");
}
} finally {
mWaitCount--;
if (mWaitCount == 0) {
// Receiver is used to listen to connectivity change and unblock
// the waiting requests. If nobody's waiting on change, there is
// no need for the receiver. The auto extension timer will try
// to maintain the connectivity periodically.
unregisterConnectivityChangeReceiverLocked();
}
}
}
}
Here is the piece of code which I got from android native source code.

private void sendSMS(String phoneNumber, String message)
{
PendingIntent pi = PendingIntent.getActivity(this, 0,
new Intent(this, SMS.class), 0);
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(phoneNumber, null, message, pi, null);
}
}
